我的SQL连接问题连接已成功与服务器建立，但随后发生错误

我的项目是在Vb和Mysql中开发的。现在我收到错误连接已成功与服务器建立，但在登录过程中出现错误



我的Db连接代码是

My Project is developed in Vb and Mysql. Now i got an error"Connection was Successfully established with the server,but then error occured during the login process"

My Db Connection Code is

Public Sub OpenDatabase(ByVal pblnOpen As Boolean)
        If GCon.State = ConnectionState.Open Then GCon.Close()
        GCon.ConnectionString = String.Format("Server={0};user id={1};password={2};database={3};Pooling=false", GstrServerName, GstrDBUser, GstrDBPass, GstrDBName)
        If pblnOpen Then GCon.Open()
    End Sub
